in region of median groove dentate; on each side a yellow supra- 

 marginal stripe usually divided by two or three dark cross-lines and 

 limited below by a narrow black marginal stripe which is more or less 

 broken into spots ; clypeus yellow, with a triangular black spot below 

 each anterior lateral eye, the apex of the spot being at the eye and the 

 base on the front margin of the clypeus; the light part of cephalo- 

 thorax in life clothed with dense white hair, that of the supramarginal 

 stripes extending also over the black marginal lines, the light side 

 stripes consequently appearing wider in live than in alcoholic speci- 

 mens, Chelicerce yellow, with some dusky markings. Labium and 

 endites and coxce of legs beneath yellow. Sternum black, usually with 

 a narrow median pale line in front; often with a row of black dots 

 along each lateral margin, and a central black stripe narrowed behind 

 and anteriorly geminated by a pale line, elsewhere being yellow. 

 Legs yellow with black annuli on all joints excepting the tarsi, the dark 

 annuli of the femora wide and predominating over the yellow, those 

 of the tibia3 of same width as the yellow bands, while those of the 

 metatarsi are distinctly narrower. Abdomeyi blackish to dark gray 

 above, sometimes of a greenish tinge; a yellow to brown lanceolate 

 stripe at base having at each side of its apex a similarly colored angular 

 spot with minute black dot at its center; on posterior portion of dorsum 

 a series of light cross-marks, each formed by the lateral confluence of 

 from two to four spots similar to those at sides of apex of basal stripe ; 

 dorsum elsewhere with many minute light dots; sides like lateral 

 portions of dorsum but with the light dots larger; venter yellow to 

 light reddish brown, with a row of irregular dark and partly confluent 

 marks along each side and a short median row of similar marks behind 

 the epigynum; in life the abdomen is densely clothed with gray and 

 brown hair. Spinnerets light brown, Epigynum light brown, the 

 posterior fovese appearing as darker blackish spots, 



Cephalothorax relatively higher in front than usual, highest at third 

 eye row, from there slanting downward to the posterior declivity, 

 concave at the dorsal groove, plane of quadrangle of posterior eyes 

 not much declined. Face as high as the length of the chelicerse or 

 slightly higher, protruding above over its lower portion ; sides slightly 

 convex or straight, sub vertical. 



Anterior row of eyes of the usual length and curvature; anterior 

 median eyes three-fourths their diameter apart, half as far from the 

 lateral eyes, their diameter from eyes of second row; anterior lateral 

 eyes three-fourths or more as large as the median, more than twice 

 their diameter from the front margin of clypeus and than their diam-
